This lens features an angle of view of approximately 50mm in 35mm format
equivalent. Adopting a compact and stylish design, the external form of this
small and lightweight lens has a diameter of just 84.0x71.0mm with a weight of
only 405g.

The optical system features a construction of 8 groups and 10 elements,
including 1 ED lens element. This lens type was adopted to represent the most
suitable lens for the GFX 50S body’s compact size, with the utmost priority
placed on resolution performance. By adopting a front group extension type for
the focus method, aberration variations due to shooting distance are
suppressed, achieving high resolution performance even when wide open, all the
way from the center to the edges of the lens.
